Agree!If you use a guide coat there will be no guessing imho. I like the 3M dry guide coat.
Is this it?3m is just overhyped and overpriced pounce powder. true pounce powder is finer and spreads better.
Used to be a standard item at any sign supply. Not used much anymore. We would put it in a cotton cloth with some cotton balls, tie it up into a bag and wack it against the sign pattern to transfer the lines. Also did the same thing with blue carpenters snap line chalk to show up on dark surfaces.I have heard this before but where do you find pounce powder? I know it's used for sewing patterns as my Mom had a pounce bag when I was growing up.
I also use a wide black marker usually on bare metal.
